| Abstract | Geranium sibiricum Linne (GSL) has been used to treat intestinal inflammation in traditional Korean folk medicine. We examined its anti-oxidative and anti-proliferative activity in the Chang liver cells. We determined that GSL glycoprotein isolated from GSL has a molecular weight of 18kDa and consists of a carbohydrate (10.45%) and protein moiety (89.55%). After confirmation of anti-oxidative activity, we investigated the changes in the production of intracellular reactive oxygen radicals (iROS) and nitric oxide in glucose oxidase-stimulated Chang liver cells, because they play a critical role for the cell proliferation as a signal mediator. The results in this study showed that GSL glycoprotein significantly reduced iROS production at 5µg/mL and increased NO production at 20µg/mL in the G/GO system (100mU/mL). Also, our finding indicated that the GSL glycoprotein ((50µg/mL) in the presence of Concanavalin A (Con A, 10µg/mL) resulted in inhibition of proliferating cell nuclear antigen (PCNA, cell proliferation marker). Taken together, GSL glycoprotein inhibits cell proliferation through modulation of intracellular ROS (iROS) and NO in the Chang liver cells. Therefore, we speculate that GSL glycoprotein has an anti-oxidative and anti-proliferative character. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
